Complies with ASTM D 4138 method A.
This destructive thickness gauge uses a tungsten carbide cutting tool to measure coating thickness on plastics, wood, aluminium, steel, concrete, glass etc.
Direct measurement of the total coating thickness or individual coatings eg. a primer and top coat.
Measurements on virtually any substrate are possible; aluminium, steel, plastic, wood, concrete or glass.
Substrate condition, coating adhesion, microscopic cracking, brittleness, blistering and intercoat
adhesion can also be measured using the built-in 50 x illuminating microscope.
A tungsten carbide cutting tool is used to incise a small precise ‘V’-shaped groove through the coating and into the substrate. The V-groove is viewed through the microscope and measured using an optical scale.
Features.
•Solid aluminium body
•For coatings up to 1250 µm
•The total thickness and individual coating thicknesses can be measured
The body of the P.I.G. is cast from aluminium and contains a microscope, a lamp and the groovecutting bit. Two legs extend from the unit on the same side as the cutting bit and are used as stabilizers when making the incision. The microscope has built-in measurement scale with major graduations in 20 microns.
Operating Steps:
| Step | Illustration | Description |
| 1 |  |
Prepare the inspecting area |
| 2 |  |
Draw a line with the marker pen on the surface |
| 3 |  |
Cut the coating vertically and make sure it is lacerated |
| 4 |  |
Read the graduation-scale with the microscope to attain thickness |
